Show Suggested Answer

Suggested Answer: B

Address Resolution Protocol (ARP) a stateless protocol was designed to map Internet Protocol addresses (IP) to their associated Media Access Control (MAC) addresses.

This being said, by mapping a 32 bit IP address to an associated 48 bit MAC address via attached Ethernet devices, a communication between local nodes can be made.

I thought it was RARP? Seems like a tricky question.

Definitely B) ARP, it's well-known for MITM vulnerabilities.

I feel like ICMP is more about error messages and not really related to address mapping, so I think it has to be ARP.

I’m a bit confused between ARP and RARP. I know both deal with address mapping, but I can't recall which is more susceptible to MITM.

I think ARP is the one that maps addresses, but I'm not entirely sure if it's the most vulnerable to MITM attacks.
